Porting a Keil uVision project to the GNU tool chain

Hello Mohit,

our GNU expert is OOO this week and admittedly I dont have much experience of GNU myself. I did a quick search online : can .obj files be linked in GNU ? this thread belwo implies not.

Hi,

I ve got the same result, can not advertise when I compile with this toolchain gcc-arm-none-eabi-4_8-2014q3. However I can run come code (ie. led blinking) and its working.
I can also confirm that the uart driver is not working with that tool chain. I used the conversion script to generate the Makefile. I did also some test with the DA14580_BEACON_3.40-2.6 sample code with no luck.

Whatever sample code I use when I set cmd->channel_map to anything but zero I seems to crash the module...

Any idea ?

我可以确认--fplugin = tree_switch_shortcut_ELF与Windows＆Mac版本的GCC-ARM-None-EABI-4_8-2014Q3不兼容，但仅在Linux上。我没有尝试使用带有选项的Linux盒子（我正在编译在Mac上。）

这是我的makefile以获取更多信息：
#
# The Makefile must define the following variables, which are used by common.mk:
# O: output directory
# STACK_SIZE: number of bytes to reserve for the stack
#Heap_size：为堆保留的字节数
# CORTEX_M: the Cortex-M model to target
# STARTUP_DEFS: define's that configure the start-up code
# CFLAGS: flags used for compilation AND linking
#ldflags：用于链接的标志
# ROM_MAP_FILE:ROM map file
# OBJ: list of object files to compile and link
# TARGET_ELF: name of the target (used in the generated images)
#

＃ 输出目录

I managed to compile with the 'tree_switch_elf' option using GCC 4.9 for mac,https://launchpad.net/gcc-arm-embedded/4.9. I make this change in the Makefile :

＃优化标志
CFLAGS += -Os -ftree-switch-shortcut

没有路ck, same crash on the module as soon as I use cmd->channel_map to select one channel for broadcast..

是否有机会在使用GNU GCC使用无线电（包括Makefile和更新链接器脚本）具有完整配置的工作项目，如有完整配置的工作项目，请使用GNU GCC？

Any help on this subject will be much appreciated !

谢谢 ：）

Hi,

还有任何更新吗？

Reading the App note B-024 seems to imply that the project builds and works, has someone gotten the radio to work with the gcc tool chain yet?

Thanks

解决方案是使用此工具链：
https://launchpad.net/gcc-arm-embedded/4.9/4.9-2015-q3-update
and change the -fplugin=tree_switch_shortcut_elf into -ftree-switch-shortcut

Possibly you'll get the next error about __weak, solve that by adding -D__weak="__attribute__((weak))" to the CFLAGS in common.mk
以及关于__nop（）的错误，通过添加-d“__ nop（）”=“asm（\”nop \“）来解决该问题。
